If you have installed ETS Inside on the same computer where ETS5 version 5.5.3 is installed, and you get an error message when trying to open a project that ETS Inside is not licensed although you have connected a dongle with a valid license for ETS Inside, please close ETS5 (if open) and restart the computer.
